If you have purchased Clip studio paint before for your Mac and you would like to use it on your Ipad pro but do not want to pay a subscription (I do not as I think it is not fair) apple has a great feature that works just fine.
Sidecar display allows you to use the program in your Ipad pro, just make sure you mirror the side car display for a full screen work surface on the Ipad. It has a slight delay but I still think it's better than paying for it.
I hope this help you guys.
Have a great day
